About Forest Buffers…
Although we may not realize it, we use many types of buffers every day; From the paper filter for our coffee maker that prevents grounds from getting into our coffee, to the insulation in our home that protects us from cold and heat, to the umbrella we may use to keep us dry on rainy days, we use many things to "buffer" or protect us.

Trees are often used as buffers where there are conflicts in adjoining land uses. Trees planted along busy highways create both a visual and noise buffer for nearby neighborhoods. Trees and forests often surround schools, parks and recreational areas to create a comforting environment. In fact, one of the best ways to protect the Anacostia River watershed and the Chesapeake Bay is to plant and conserve trees as forest buffers along their banks and shorelines.

Streamside or riparian (derived from a Greek word meaning "on or near the shore") are one of the most effective and least expensive ways to protect the Anacostia River and its tributaries. Riparian buffers filter sediment and pollutant runoff from non-point sources such as streets, storm drains, and parking lots, and provide extensive root systems that "lock" soil particles together, slowing erosion.

The organic layer on the riparian forest floor is made up of leaves, twigs and fallen logs create a natural "sponge" that stores water and nutrients, and converts fertilizers and pollutants into environmentally-safe compounds that can be absorbed by trees and vegetation. In addition, riparian forests shade streams and cool water temperatures, providing a desirable habitat for entire ecosystems of macroinvertebrates, fish, and mammals.

The 3-Zone Buffer System…

The Maryland Department of Natural Resources - Forest Service promotes the establishment of a 3-zone buffer system to protect the Anacostia watershed and other tributaries of the Chesapeake Bay. In an ideal setting, the 3-zone buffer system provides all of the benefits that the forest has to offer; an effective buffer against non-point source pollution, habitat for fish and wildlife, areas for recreation, and a renewable source of forest products. Let's take a look at how the 3-zone buffer system works:
